EXHIBIT 4.5

FORM OF “TYPE 3” HOLDER VOTING AGREEMENT

This Holder Voting Agreement (this “Agreement”) is made as of the          day of                     , 20    , by and among Facebook, Inc., a Delaware corporation (the “Company”),                     (each, together with its successors, a “Stockholder” and collectively, “Stockholders”), and Mark Zuckerberg (“Proxyholder”).

RECITALS

A. Stockholders are expected to purchase shares of Class B Common Stock of the Company from             (the “Common Holder Shares”) and are party to that certain Sixth Amended and Restated Voting Agreement by and among the Company, the Founders (as defined therein), Peter Thiel and the Investors (as defined therein), dated as of November 20, 2009 (the “Investor Voting Agreement”). Any acquisition of the Common Holder Shares shall occur pursuant to the Stock Transfer Agreements to be identified on Exhibit A hereto (each a “Stock Transfer Agreement” and, together, the “Stock Transfer Agreements”) which agreements shall be in form and substance satisfactory to the Company and Proxyholder. As any Common Holder Shares are acquired pursuant to a Stock Transfer Agreement, such agreement will be identified on Exhibit A hereto, as updated by the Company.

B. This Agreement, among other things, requires Stockholders to vote all Common Holder Shares and all shares of capital stock of the Company that a Stockholder hereafter acquires or as to which a Stockholder hereafter acquires the right to exercise voting or dispositive authority (together, all such shares referred to in this sentence and any securities of the Company issued with respect to, upon conversion of, or in exchange or substitution of such shares, the “Shares”) in the manner set forth herein. For the avoidance of doubt, the term “Shares” shall not include any shares of capital stock of the Company that (i) a Stockholder or any affiliate of a Stockholder holds, or as to which a Stockholder or any affiliate of a Stockholder exercises voting or dispositive authority over, as of the date hereof, including, without limitation, shares of             , or (ii) any securities of the Company issued as dividends, with respect to stock splits or the like, upon conversion of, or in exchange or substitution of such shares (collectively, the “Excluded Stock”).

C. This Agreement is being entered into in exchange for a payment of U.S. $100 in cash from Proxyholder to each Stockholder and for other good and valuable consideration, the sufficiency of which is hereby acknowledged and agreed.

AGREEMENT

The parties agree as follows:

1. No Conflict with Investor Voting Agreement. In the event of a conflict between the terms and provisions of this Agreement and the terms and provisions of the Investor Voting Agreement, the terms and provisions of the Investor Voting Agreement will prevail, and Proxyholder or Stockholders, as the case may be, shall be obligated to vote the Shares in accordance with the Investor Voting Agreement.

2. Voting Arrangements. Stockholders hereby agree that Proxyholder shall have the right to vote all the Shares, in his sole discretion, on all matters submitted to a vote of stockholders of the Company at a meeting of stockholders or through the solicitation of a written consent of stockholders (whether of any individual class of stock or of multiple classes of stock voting together) except for:

2.1. Any issuance, or series of related issuances, of capital stock in a capital raising transaction by the Company that is submitted for stockholder approval in which the number of shares of capital stock so issued will exceed 20% of the total number of shares of capital stock of the Company outstanding immediately prior to such issuance; and

2.2. Any matter, the outcome of the vote on which would disproportionately, materially and adversely affect a Stockholder, as compared to other holders of the same class(es) of capital stock of Company, provided that, subject to Section 2.1, increases in the authorized number of shares of preferred stock generally, or the authorized number of any class of preferred stock of the Company or the issuance of securities of the Company senior to such class of preferred stock will not be viewed as having such an adverse effect.

With respect to the excepted matters described in Sections 2.1 and 2.2 above, such Stockholder shall have the right to (i) instruct Proxyholder in writing as to the manner in which the Shares shall be voted or (ii) vote the Shares in person or by action by written consent, as applicable, in which case such Stockholder shall notify Proxyholder in writing that it intends to so vote. In addition, Proxyholder shall not have any right to waive notice by the Company to such Stockholder. Such instruction or notice shall be provided to Proxyholder at least five (5) days prior to the date of any meeting of stockholders at which such matter is to be voted upon or as promptly as reasonably practicable upon such Stockholder becoming aware that such matter is to be acted upon by written consent. In the event that such Stockholder does not so instruct Proxyholder or notify Proxyholder of its intention to so vote or act by written consent, Proxyholder shall abstain from voting the Shares in respect of such matters.

3. Illustrative Examples. Matters on which Proxyholder shall be entitled to vote, pursuant to Section 2 include, but are not limited to, the following, which are presented here solely by way of example:

3.1. Election, replacement or removal of directors of the Company (each, a “Director”);

2

3.2. Sale or other disposition of all or substantially all of the Company’s assets, provided, that any distribution to Company stockholders of the proceeds of such sale or disposition are made in accordance with the Company’s certificate of incorporation, as then in effect;

3.3. Mergers of, or acquisitions by, the Company or its subsidiaries that are submitted for stockholder approval;

3.4. Adoption by the Company of a rights plan or similar takeover defensive arrangements, or amendments thereof, which plan provides that a triggering event will occur only upon the acquisition by a stockholder of 15% or more of the Company’s shares of voting capital stock; and

3.5. Adoption by the Company of a two-class capital stock structure (a “Dual Class Structure”) in which one class of capital stock has, among other things, enhanced voting rights, including but not necessarily limited to multiple votes per share (“Heavy Vote Stock”), and the other class of capital stock does not (“Low Vote Stock”), provided, that, the shares of capital stock held by Stockholders at the time of adoption of such structure are entitled to be converted into Heavy Vote Stock.

4. Stockholders to Abstain from Voting. Stockholders agree that, unless Proxyholder provides explicit written instruction to vote the Shares under this Agreement or Proxyholder provides explicit written notice that a Stockholder shall be permitted by Proxyholder to vote in a manner other than as Proxyholder instructs, Stockholders shall abstain from voting any of the Shares (in person, by proxy or by action by written consent, as applicable) on all matters other than with respect to the matters set forth in Section 2.1 and 2.2.

5. Irrevocable Proxy and Power of Attorney. To secure Stockholders’ obligations to vote the Shares in accordance with this Agreement and to comply with the other terms hereof, Stockholders hereby appoint Proxyholder, or his designees, as Stockholders’ true and lawful proxy and attorney, with the power to act alone and with full power of substitution, to vote or act by written consent with respect to all the Shares in accordance with the provisions set forth in this Agreement, and to execute all appropriate instruments consistent with this Agreement on behalf of Stockholders. The proxy and power granted by Stockholders pursuant to this Section 5 are coupled with an interest and are given to secure the performance of Stockholders’ duties under this Agreement. The proxy and power will be irrevocable for the term hereof. The proxy and power will survive the merger, consolidation, conversion or reorganization of a Stockholder or any other entity holding the Shares.

6. Additional Representations, Covenants and Agreements.

6.1. Transfers by Stockholders.

(a) Stockholders hereby acknowledge that Proxyholder is an intended third-party beneficiary of the Fourth Amended and Restated Right of First Refusal and Co-Sale Agreement by and among the Founders (as defined therein), the Company and the Investors (as defined therein) dated as of November 20, 2009, as amended from time to time (the “ROFR Agreement”) and the Stock Transfer Agreements.

3

(b) Stockholders further acknowledge that the Common Holder Shares are subject to voting agreements, as identified on Exhibit B hereto (the “Original Voting Agreements”), in favor of Proxyholder regarding the voting or transfer of such shares. Stockholders agree that the Original Voting Agreements shall remain in full force and effect, except as set forth herein; provided, however, that the terms of the Original Voting Agreements shall be suspended and not apply to the Common Holder Shares (or to Stockholders with respect to the Shares) for so long as this Agreement remains in effect. Except as otherwise expressly provided in this Agreement, in the event that this Agreement is terminated for any reason (other than pursuant to Section 7.1 (c)), the suspension of the terms of the Original Voting Agreements shall cease and such Original Voting Agreements shall again apply to the Common Holder Shares (and to Stockholders with respect to the Shares and not to any Excluded Stock). In the event that this Agreement is terminated pursuant to Section 7.1(c), neither this Agreement nor any Original Voting Agreement shall apply to any Shares or Stockholders. In the event of a conflict between the terms and provisions of either or both of this Agreement or any Original Voting Agreement and the Investor Voting Agreement, the terms and provisions of the Investor Voting Agreement shall prevail.

(c) Pursuant to the Stock Transfer Agreements and Section 6 of the ROFR Agreement, a Stockholder may not transfer, assign, pledge or otherwise dispose of or encumber the Shares (collectively, a “Transfer”) without the prior written consent of the Company, unless otherwise permitted by the Stock Transfer Agreements and the ROFR Agreement.

(d) If a Stockholder’s Transfer of Shares is permitted under the terms of the Stock Transfer Agreements and the ROFR Agreement or is otherwise consented to by the Company pursuant to the Stock Transfer Agreements and the ROFR Agreement, such Transfer shall not take effect until the pledgee, transferee or donee of such Shares (the “Transferee”) furnishes Proxyholder and the Company with a written agreement to be bound by the terms of this Agreement (an “Assumption Agreement”) and any additional agreement required under any other applicable agreements between the parties hereto, it being understood and agreed that the Company shall be entitled to issue stop transfer instructions in respect of such Shares to preclude any transfer of Shares in contravention of the foregoing. Notwithstanding the foregoing, following the completion of a firm commitment underwritten public offering by the Company (the “Initial Public Offering”) under the Securities Act of 1933, as amended (the “Securities Act”), the Transferee shall not be required to enter into an Assumption Agreement (and the Shares shall no longer be subject to the restrictions of this Agreement or any Original Voting Agreement) if:

(i) at the time of such Transfer the Company has a Dual Class Structure and a Stockholder is transferring (x) Heavy Vote Stock that, upon completion of such Transfer, shall automatically become Low Vote Stock, or (y) Low Vote Stock; or

(ii) the Shares of capital stock being transferred by a Stockholder, in either a single transaction or series of related transactions, represent less than 3.17% of the aggregate number of shares of the Company’s voting capital stock then outstanding.

4

For clarification purposes, Shares Transferred after an Initial Public Offering and in accordance with Section 6.1 (d) shall no longer be subject to this Agreement or any Original Voting Agreement and the Transferee shall not be treated as a “Stockholder” for purposes of this Agreement. Except as set forth in the prior sentence, upon satisfaction of the provisions of this Section 6.1, such pledgee, transferee or donee shall be treated as a “Stockholder” for purposes of this Agreement.

6.2. Priority of Transfer. Stockholders acknowledge and agree that in the event that a Stockholder proposes to Transfer Shares to a third party at a time when such Stockholder holds Shares of the Company’s capital stock that are subject to this Agreement, but not the Original Voting Agreements (the “Single Agreement Shares”) and shares that are subject to both this Agreement and the Original Voting Agreements (the “Dual Agreement Shares”), it will only Transfer a portion of the Dual Agreement Shares it then holds that is no greater than the fraction represented by the number of Single Agreement Shares being transferred divided by the total number of Single Agreement Shares held by such Stockholder immediately prior to such Transfer.

6.3. Legends. The Company shall cause each certificate representing the Shares to bear the following legend, in addition to any legends that may be required by state or federal securities laws or the terms of any voting or other agreements that apply:

THE SHARES EVIDENCED HEREBY ARE SUBJECT TO A HOLDER VOTING AGREEMENT BY AND AMONG THE COMPANY AND CERTAIN STOCKHOLDERS OF THE COMPANY, DATED AS OF                     , 20    (A COPY OF WHICH MAY BE OBTAINED FROM THE COMPANY) WHICH INCLUDES PROVISIONS POTENTIALLY RESTRICTING THE STOCKHOLDER’S RIGHT TO VOTE OR TRANSFER AN INTEREST IN THE SHARES EVIDENCED HEREBY, AND BY ACCEPTING ANY INTEREST IN SUCH SHARES THE PERSON ACCEPTING SUCH INTEREST SHALL BE DEEMED TO AGREE TO AND SHALL BECOME BOUND BY ALL THE PROVISIONS OF SAID HOLDER VOTING AGREEMENT.

6.4. Stock Splits, Dividends, Etc. In the event of any issuance of shares of the Company’s voting securities hereafter to a Stockholder as a result of such Stockholder’s ownership of Shares (including, without limitation, in connection with any stock split, stock dividend, recapitalization, reorganization, or the like), such shares shall automatically be deemed “Shares” hereunder and shall be endorsed with the legend set forth in Section 6.3. Section     of the Original Voting Agreement entered into with                      provides that any of the Company’s voting securities issued in connection with a stock split, dividend, recapitalization, reorganization or the like with respect to securities subject to such Original Voting Agreement shall automatically become subject to the restrictions set forth in the Original Voting Agreement (the “Stock Split Provisions”). For the avoidance of doubt, the Stock Split Provisions shall apply only to the Shares and not to Excluded Stock and shall not in any manner encumber the Excluded Stock or any securities issued as a stock split, stock dividend, recapitalization, reorganization or the like on Excluded Stock.

5

6.5. Specific Enforcement. It is agreed and understood that monetary damages would not adequately compensate an injured party for the breach of this Agreement by any party, that this Agreement shall be specifically enforceable, and that any breach or threatened breach of this Agreement shall be the proper subject of a temporary or permanent injunction or restraining order. Further, each party hereto waives any claim or defense that there is an adequate remedy at law for such breach or threatened breach.

6.6. Securities Laws, Rules and Regulations. Stockholders, the Company and Proxyholder agree and understand that Stockholders, the Company and/or Proxyholder may become subject to the registration and/or reporting requirements, rules and regulations of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Securities Act and/or any state and federal securities laws (collectively with the Exchange Act and the Securities Act, the “Securities Laws”). Stockholders, the Company and Proxyholder agree to use their respective commercially reasonable efforts to comply with the Securities Laws and to reasonably assist each other in complying with the Securities Laws in a timely and prompt manner. Such compliance may include, for example and without limiting the foregoing, the filing and updating and maintaining of Form 13G and/or Form 13D under the Exchange Act.

6.7. Other Arrangements. During the term of this Agreement a Stockholder will not, in its capacity as a holder of the Shares only (and not as a holder of Excluded Stock), without Proxyholder’s written consent:

(a) offer, seek or propose to acquire or cause to be acquired, any ownership of any assets or business of the Company or any of its subsidiaries, or seek to propose or propose, whether alone or in concert with other persons, any tender offer, exchange offer, merger, business combination, restructuring, liquidation, recapitalization or similar transaction involving the Company or any of its subsidiaries;

(b) make, or in any way participate in, any “solicitation” of “proxies” (as such terms are defined in Rule 14a-1 under the Exchange Act) with respect to the voting of any securities of the Company or any of its subsidiaries or seek to advise or influence other stockholders the Company with regard to the voting of their securities of the Company;

(c) form, join, or in any way become a member of a 13D Group with respect to any voting securities of the Company or any of its subsidiaries (where “13D Group” means any “group”, within the meaning of Section 13(d) of the Exchange Act, formed for the purpose of acquiring, holding, voting or disposing of voting securities of the Company other than a Stockholder and its “affiliates”, as such term is defined in the Exchange Act);

(d) nominate any person as a director of the Company who is not nominated by the then incumbent directors, propose any matter to be voted upon by the stockholders of the Company or initiate or vote in favor of a call for a special meeting of stockholders of the Company; or

In addition, during the term of this Agreement, a Stockholder shall promptly, but in any event within three (3) days, notify the Company and Proxyholder in writing of any acquisition by such Stockholder of shares of capital stock of the Company (other than the acquisition of shares of capital stock of the company issued in relation to Excluded Stock or with respect to, upon conversion of, or in exchange or substitution of shares of capital stock of the Company held by such Stockholder).

6.8. Proxyholder’s Liability. In voting the Shares in accordance with Section 2 hereof, Proxyholder shall not be liable for any error of judgment nor for any act done or omitted, nor for any mistake of fact or law nor for anything which Proxyholder may do or refrain from doing in good faith, nor shall Proxyholder have any accountability hereunder, except for his own bad faith, gross negligence or willful misconduct. Furthermore, upon any judicial or other inquiry or investigation of or concerning Proxyholder’s acts pursuant to his rights and powers as Proxyholder, such acts shall be deemed reasonable and in the best interests of Stockholders unless proved to the contrary by clear and convincing evidence.

6.9. Consideration. In connection with this Agreement and as partial consideration for the obligations of Stockholders hereunder, Proxyholder shall pay (by check, cash or other valid consideration) to each Stockholder the sum of U.S. $100 in the aggregate.

6.10. Notice Waiver. Pursuant to Section 2(d) of the Original Voting Agreements, Proxyholder has a right to 5 business days notice prior to the Transfer of shares subject to the Original Voting Agreements. Proxyholder hereby waives such notice with respect to Common Holder Shares purchased on or before December 21, 2009.

7. Termination.

7.1. Termination Events. This Agreement shall terminate:

(a) upon the liquidation, dissolution or winding up of the business operations of the Company;

(b) upon the execution by the Company of a general assignment for the benefit of creditors or the appointment of a receiver or trustee to take possession of the property and assets of the Company;

(c) in the sole discretion of Proxyholder, upon the express written consent of Proxyholder (which he shall be under no obligation to provide);

(d) upon the death or permanent and substantial incapacity of Proxyholder, as determined in good faith by the Company’s board of directors, unless Proxyholder is actively contesting such determination of incapacity; or

(e) Six (6) months after the later of the date on which Proxyholder (i) ceases to be Chief Executive Officer (“CEO”) of the Company, and (ii) is no longer Actively

7

Engaged in the management of the Company, where “Actively Engaged” is defined as Proxyholder (I) being a Director, (II) devoting substantially all of his business efforts to the Company, and (III) being the beneficial owner of at least 50% (the “Threshold Amount”) of the shares of capital stock of the Company beneficially owned by him as of May 26, 2009 (as adjusted for any stock split, stock dividend, recapitalization, reorganization or the like). For the purposes of the foregoing definition of Threshold Amount, the term beneficial owner shall have the meaning set forth in Rule 16a-1(a)(2) under the Exchange Act. Notwithstanding the foregoing, the date of termination of this Agreement pursuant to this Section 7.1 (e) will be 12 (twelve) months after such later date if (x) Proxyholder is actively contesting his removal as CEO or Director, or (y) has ceased to be Actively Engaged due to having taken a leave of absence for medical reasons, provided, however, that if at any time Proxyholder is not CEO (and he is not actively contesting his removal as CEO) and he ceases to be Actively Engaged due to his owning less than the Threshold Amount, this Agreement shall terminate immediately upon the date as of which he ceases to own less than the Threshold Amount.

For clarification purposes, the Original Voting Agreements shall not apply and be terminated with respect to any Shares Transferred in accordance with the immediately preceding sentence and any Transferee shall receive such Shares without the restrictions of the Original Voting Agreements.
